Description

  The present invention relates to chopsticks, and more particularly to a paper chopstick made of paper material.

  Currently, disposable chopsticks are among the most commonly seen disposable tableware. Disposable chopsticks are convenient to use and are usually wooden products that are thrown away once used and do not need to be washed, so they are easy to use and widely accepted by people and are indispensable for outdoor dining Yes.

  However, environmental awareness has increased in recent years, and the use of disposable chopsticks has caused recycling problems. The chopsticks themselves, as well as the packaging of the vinyl and paper materials that wrap them, also lead to an increase in the amount of garbage, and the use of bleaching agents cannot be avoided even during the manufacturing process of disposable chopsticks, so there are numerous drawbacks to disposable chopsticks It can be said.

  Therefore, if paper chopsticks can be made from paper materials, the disadvantage of using bleach in the manufacturing process of wooden disposable chopsticks can be avoided, and recycling is also more convenient than wooden disposable chopsticks. Chopsticks are the best solution that can overcome the shortcomings of current wooden disposable chopsticks.

  An object of the present invention is to provide a paper chopstick.

  The paper chopsticks of the present invention include a paper chopstick body made of a paper material, wherein the paper chopstick body has a wound surface, forms a spiral structure, the paper chopstick body has a hollow shape, and a rear end. Is larger than the circle diameter of the front end, and the hardness of the front end is higher than the hardness of the rear end.

  In the best embodiment, a multi-layer paper material is formed through a folding process.

  In a best embodiment, the paper material is waterproof paper.

  In a best embodiment, a single waterproof film can be applied to the surface of the paper chopstick body.

  In the best embodiment, the paper chopstick body can be fixed by adhesion, engagement or crimping.

  The present invention can manufacture paper chopsticks with a strengthened structure through multilayer paper materials, and the manufactured paper chopsticks can avoid the use of bleach in the manufacturing process of wooden disposable chopsticks, and can be recycled more easily than wooden disposable chopsticks, and It has the advantages that it can be manufactured in large quantities by a machine, can reduce costs, can be applied easily, and can be widely applied.

  Other technical contents, features, and effects of the present invention will be described more clearly and in detail with reference to the drawings and the best embodiments.

  FIG. 1 shows a three-dimensional external view of the paper chopsticks of the present invention. The paper chopsticks of the present invention include a paper chopstick body 1 made of a paper material, of which the paper chopstick body 1 has a wound surface 11 (a surface 11 formed by wrapping), and has a spiral structure. The paper chopstick body 1 is hollow, the circle diameter of the rear end is larger than the circle diameter of the front end, and the hardness of the front end is higher than the hardness of the rear end.

The structural molding (structural molding process) of the paper chopstick body 1 is shown in FIGS. 2A to 2D. First, as shown in FIG. 2A, the paper material is first folded to the left to form a first fold line 12 in a general facility, and then further folded to the right as shown in FIG. 2B. A second fold line 13 that is in contact with one end (connect, touch each other, join) is formed. Subsequently, as shown in FIG. 2C, after folding again to the left to form a third fold line 14 adjacent to another end of the first fold line 12, as shown in FIG. 2D, the upper end of the paper material The fourth fold line 15 is formed by folding the fixing portion 16 backward, and the fourth fold line 15 intersects with the second fold line 13 and the third fold line 14.

  As shown in FIG. 2E, after further folding back the fixing portion 16 on one side of the fourth fold line 15, the multi-layer paper material having the above folding process completed is wound in a winding facility to form a tubular shape, The fixing part 16 is left. Finally, as shown in FIG. 2G, it is fixed by adhesion, engagement or pressure bonding so that the wound tubular shape cannot be unwound. Thus, the paper chopstick body 1 is formed.

The paper chopsticks provided by the present invention have the following advantages over other prior art.
1. The present invention can manufacture paper chopsticks with a strengthened structure through multilayer paper material, and the manufactured paper chopsticks can avoid the use of bleaching agent in the manufacturing process of wooden disposable chopsticks and can be recycled more easily than wooden disposable chopsticks. .
2. The paper chopsticks of the present invention have advantages such as environmental protection features, that can be manufactured in large quantities by a machine, can reduce costs, and can be easily applied to a wide range of processes.
3. The paper material of the present invention is folded to increase the hardness of the paper chopsticks, the tip of the paper chopsticks is the hardest and the middle part is relatively hard, so that the same usage method as a general usage habit can be achieved. The middle part of the paper chopsticks is relatively hard so that the user can grip and apply force, and since the tip of the paper chopsticks is the hardest, it can be stabbed into the food or cut into the food.

  Although the present invention has been disclosed through the above-described embodiments, the above-described embodiments do not limit the present invention, and those skilled in the art will understand the above-described technical features and embodiments of the present invention, and then the gist of the present invention. Some changes and modifications may be made without departing from the scope. Therefore, the protection scope of the present invention conforms to the description in the scope of claims.
